Pronnnn, a, lnitetl States, residing in I .e eou'nty Hartford and hilnae oi Qonneelie" heve invented certain improvements in Typeiers or other wise-shite g; n Wi-itii'ig machines, to i or to upper ehei'olore two independent shift keys one at each side of the the righhhencl key en to upper case and locked while the left-hand shift key served t iten.

f the p *incipol objects of my inveniio 31x rule increased facilities for lionv is shifting the 1 ten and platen frame or other wee-shittingdevice, and particularly to 3'. "e convenience of eileoting a reunio oil platen, without how ie usual advantage of lockeaten by the mere depression of a inn the s2.v v i 'i iect of the invention is to for releasing the platen ien it lies been looked. these e contrive to elevate or ehiit the platen or platen frame by means of a. temporary shift-key at either side of Pl-llfi lqeyooarch so that either of said keys may he (lepr cl and held down during the Writing of :i ingle capital letter, end then released to tore the shift mechanism to nornml lOW8T-('zl I(' position. In addition to said keys, l provide 21 third key, preferably at the right-hand side of the keyboard, which may be depressed to botli'shift and loirlt the platen in upper-case position. This look may he released by depression of either of the first-mentioned temporary shiftlCGYS.

dog. It will be understood that this short lever serves to bear down the first key-lever to shift the platen. ln other wort (he platen may be shifted and lielil locked by the lirst-n'ientioned key, or it may he sliiltell temporarily by the secondonentionerl key,

since the finger on the latter silences the dog or holds it out of action. [it the left hand end of the keyboard the usual temporary shift key, having a connection to re lease said (log, this shift-key being" arranged as usual in the front bank oi keys! Thus the operator may temporarily shift the platen without looking the same, by depression of either of the keys that are mounted at the ends of the front bank of keys, thereby greatly facilitating the operation of the machine: while at any time the platen iiiziy be shifted and locked by merely depressing the locking key; and thereafter the platen may again be released by depressing either one of the aforesaid temporary shilt keys. in the accompanying ('lrewihg 's l igure 1 IS a perspective \lGW showing the platen and one form of my improved shifting; devices.

(lepressingsnid key, the type keys ire caused to "CJFHQ capital letters tlllll upon releasing he key $5, iheplateii (lroppe l io'iiornuil position, so that the keys will Write lower Case letters. At the right hand side of the machine is a similar arm 11 to operate a similar arm 12 9f the rocking frame, said arm 11 extending-but from a lever 13, which is loosely pivoted upon the rod 10, and carries at its forward endla key 1a, depression of which will throw the plate" frame up to the dotted line position, at Fig. 1. When the key 14: is depressed, a hook or dog 15 catches over a pin 16 which projects from the side of thelever 13, thereby holding down said lever and holding the platen in,the upper position, so that a line of capital letters may be Written. The dog 15 is rigidly secured upon a rock shaft 17 and a spring 18 tends constantly to move the dog 15 backwardly, so that it will catch over the pin 16 when the latter is sufiiciently depressed. Said temporary shift key 8 has means to release the lever 13 from the control of the dog 5, so as to permit the platen frame to drop. A pin 19 projects from the side of the lever 9 to engage an upstanding cam arm 20 also fixed upon the rock shaft 17 so that at every deression of'said key 8, 'theshaft 17 is rocked and the dog 15 carried forwardly, thereby releasing the pin 16 and lever 13 and permits ting theplaten frame to drop.

I pivot at 21 upon the shift key lever13 an auxiliary short le ver 22 hearing a key 23,

the locking key 14:. The

which is in front-of lever 22 extends back from the fulcrum 21, and is formed with ears 24, 25, to catch over the top and bottom of the lever 13 to limit the play of lever 22 thereon. The auxiliary lever 22 is also formed with a downwardly extending finger 26, the rear edge 27 Whereof engages a pin28 provided upon the dog 15 below the rock shaft 17. Depression of the key 23 turns the auxiliary lever 22 about the pivot 21, and the finger 26 is-swung backwardly. to engage pin 28, and thereby rock the dog 15 forwardly to an idle position, preventing it from catching over the pin 16 on the shift lever 13. Hence the key 23, as well as the key 8, may be used to release the lever 13 from the control of the (log. The key 23 may also be used as a temporary shift key in the same manner as the key 8, since the ear 2% enables the key 23 to swing down the lever 13, While the finger 26 silences the dog 15, so that when the key 23 is released, the platen frame drops.

The keys 8 and 23 are at the extreme ends of the front bank of type eye 29. The next rear bank'is seen at 250, the next at 31, and the rear-most bank at 132, Fig. 3. The key 14 is preferably in the next to the roar bank, that is, at the right hand end of the bank of keys 31. Thus, shift key 14 may be depressed at any time to shift and lock the platen frame, While either key 8 or 23 may be employed to unlock the same. Moreover either of said keys 8 0'123 may be used at any time as a temporary shift key.

Having thus described myinvention, I claim:

In a typewriting machine, the combination with a case-shifting member, of a key lever at each side of the keyboard to shift said shifting member, one of the key levers, means connecting the other 'key lever with the dog to release the same upon operation of said other or second key lever, and an auxiliary key lever hung on the first key lever to release the dog.
